DIE-PRESS.

To all whom it may concern Be it known that I, FRED VVAITE, a subject of the King of Great Britain, and a resident of Otley, in the county of York, England, have made certain new and useful Improvements in Die-Presses, of which the following is a specification.

The invention relates more particularly to improvements in means for producing accurate register between the die and work in die presses where the work is placed upon a feed plate in position over the die prior to being impressed between the die and the counter or platen.

The present improvement contemplates the lowering of the feed plate before the impression is effected so as to bring the top of the feed plate to such position that it does not extend above the top of the die when the impressing is being efiected and the raising of the feed plate thereafter sulficient to permit the die to move underneath the same, whereby the die may be inked and then wiped.

As showing a specific embodiment of my invention reference is made to the drawings forming a part of the specification and in which drawings 1 Figure 1 represents a side elevation of my improved die press; Fig. 2 is a detail view of the feed plate used therein; and Fig. 3 is a sectional view of Fig. 2 on line 8-3.

The main frame of the machine is designated by reference letter A and upon this frame there are carried five important operating elements of the machine, namely Mechanism B for reciprocating vertically the counter or platen; inking mechanism C, including a movable ductor roller and a movable die engaging roller; mechanism D for reciprocating the die from .impressing position to the inking mechanism and back to impressing position; wiper mechanism E which is out of the path of the die when the die is traveling toward inking position but which comes in position to wipe off the ink from the die as the latter travels from inking position and mechanism F upon which the work is placed prior to being impressed between the counter and die, said mechanism including means for reciprocating vertically a feed plate.

- All of the mechanisms above enumerated are operated from a common shaft 1 driven. by means of the spur gears 2 and 3, the

latter of which is on the shaft which carries the driving pulley 4.

The mechanism B for reciprocating the counter comprises a set of toggles 5 and 6, the upper one of which is pivoted to the frame and the lower one of which is pivotally connected to the counter or platen holder 7. This toggle is operated by the lever 8 and link 9, the lower end of which carries a roller 10 which lies in the slot of the impression cam and is held in proper position therein by the swinging end of pivoted link 11. e

The mechanism C for inking the die comprises the usual ink fountain including an ink fountain roller 12, a ductor roller 12 and a die engaging roller 12'. The ductor roller and the die engaging roller are movable from the position in which the ductor roller receives ink from the fountain roller to the position where the die can be inked when passing under the rollers and in engagement with the die roller. The mechanism for accomplishing said movement of the ductor and die engaging rollers comprises a pivoted arm 13 carrying the ductor and die engaging rollers, the arm 14:, arm 16, a yieldable link connecting member 15 between arms 14C and 16, and the arm 17 carrying roller 18 which is in engagement with the ductor cam on the shaft 1.

The die mechanism D comprises a die box or carriage 19 which is reciprocated on the horizontal guideways 19 from the impressing position where it rests during the impressing operation on cross rail 19 to position where the die can take on ink, such position being indicated by dotted lines at d.

The mechanism for causing this reciprocation of the die box or carriage comprises a link 20 connected to the die carriage and the free end of arm 21, pivoted at 21*. The proper reciprocatory movement of the arm 21 from the shaft 1 is accomplished by means of the crank 22, carried by the shaft, the connecting link 23, arms 24 and 25 and the yieldable link connection 26 between arm 21 and the free end of arm 25.

The wiper mechanism E comprises a support 27 over which the paper, for accomplishing the wiping of the die, passes and which support holds the paper in engagement with the die during the wiping opera- 1 tion. The path of the paper is indicated by the dot and dash lines and the movement of re feed mechanism F comprises a feed plate 39 having the die receiving opening 39". This plate is supported on the upper end of vertical members 40 slidable in ways "'1 at their upper end and connected at the ower end to arm $12 which is caused to re ciprocate by means of the arm 43 carrying 'oller which is in engagement with the eed plate cam.

The operation of'the machine is as fol lows: While the die is being inked and wiped and the feed plate is in elevated position a piece of work to be impressed is placed upon the feed plate, the counter moves downward, but before it reaches impressing position the feed plate has been lowered to a position where the top surface is level with or just below the top of the die and it remains there until after the counter has left impressing position. lVhen the counter has left impressing position the feed plate rises sufficiently to lift the work from the die and permit the die to move horizontally thereunder back to inking posit-ion. Before the die reaches the end of its rearward travel the ductor roller will be in position to engage the die and will remain in such position until after the die moves thereunder on its forward stroke Thus it will be seen that the die is inked on both directions of its movement. After the die leaves the ductor roller on its forward stroke it comes into engagement with the wiper, which has by this time moved in proper po sition to engage the die and all surplus ink is thereby removed from the die, leaving the die in proper condition for the next impressing operation. At the termination of the forward stroke the die is in proper position to carry out the next impressing operation and the cycle of operation is completed.

It is obvious that various forms and modifications may be made without departing from the spirit and scope of my invention.

1 claim as my invention:

1. In a printing press a horizontal guideway, a die, a reciprocating die carrier slidably mounted on the guideway and always carried and supported thereby, an inking mechanism which inks the die when near one extremity of its travel, a vertically moving counter which can impress the work upon the die when the latter is in impressing position at the other extremity of its travel, a rising and falling table which rises above the top of the die prior to the latter being moved toward inking position from impressing position and which table is lowered after the die has been brought to position where the inking operation can be carried out, so that the top of the table is at least as low as the general surface of the top of the die and a common means for operating the die, counter and feed table in the manner above specified.

In die press the combination of a vertically movable counter, a horizontally movable die, a vertically movable feed plate or table and common operating means for lifting the counter as the die moves from impressing position, for forcing the counter downwardly when the die is in impression receiving position, for raising the table after the impression has been effected, whereby the die can travel horizontally below the table, for lowering the table after the die is in impression receiving position and for maintaining the top of the table below the top of the die until after the impressing operation has been started to be effected.

3. In a die press the combination of a counter movable to and from impressing position, a die movable to and from impressing position in a direction at an angle to the direction of movement of the counter, a feed plate movable in the same direction that the counter moves and a common operating means for moving the counter and die from impressing position, for moving the table toward the counter prior to the die being moved from impressing position and for moving the table backward from the counter, prior to the impressing of the work between the die and counter1 so that the face of the table will not extend forward beyond the face of the die when the impressing operation is started to be effected.

4. In a die press the combination of a. vertically movable platen or counter, a die below the platen, a die carrier for moving the die laterally from impressing position to die inking position, a movable feed plate or table and common operating means constructed and arranged so as to move the counter toward impressing position, so as to move the die from impressing position to inking position as the counter moves from impressing position and so as to raise the table after the impressing position has been effected in order that the die can move laterally from impressing position toward inking position and to lower the feed table before the impressing operation is eifected, so that the top of the feed plate or table is at least as low as the top of the die during the impressing operation.

5. In a printing press a vertically movable counter, a horizontally reciprocating die, a rising and falling feed table having a die receiving opening therein and common operating means for the counter, die and table, the parts being constructed and arranged so that When the counter reaches impressing position and While the counter remains in said position the top of-the feed table Will be as lOW as the top of the die which at that time is located under the counter, and so that the table will be raised prior to the die being removed from impressing position in order to permit the die to move horizontally from said impressing position. v
